Application August 1, 1940, Serial No. 349,323

(ci. .2o-162) 4 Claims'.

This invention relates to a blade holder, and

it is an object of the invention to provide a device of this kindwherein the blade, such as' a single edge razor blade, may be readilyextended a desired distance out from the holder and effectively heldvinv said' selected extended position and wherein the holder provides acasing for housing the blade when not in use. y

The invention consists in the details of construction and. in thecombination and arrangement of ther several parts of my improved bladeholder whereby certain important advantages vare attained and the devicerendered simpler,

less. expensive` and. otherwise more convenient land advantageous foruse, as will be hereinafter more fully set forth.

The novel features of. my invention will hereinafter bedenitel-yclaimed.

l'n order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanying drawing,wherein:

Figure 1 is a view in side elevation of a holder constructed inaccordance with an embodiment of my invention with ythe associated bladeextended for use;

Figure 2 is a sectional view taken substantially on the line 2 2 ofFigure l;

Figure 3 is a view substantially the same as Figure 2 but showing theparts in their fully compacted relation;

Figure 4 is a sectional View taken substantially on the line 4-4 ofFigure 3;

Figure 5 is a sectional view taken substantially on the line 5 5 ofFigure 4.

As disclosed in the accompanying drawing, my improved holder comprisesan elongated sheathing or casing I substantially at in form and whichhas its opposite -end portions open. slidable through the casing I is anelongated flat member 2 of a width substantially equal to the internalwidth of the casing I and in the present embodiment of my invention theportion of the member 2 within the casing I has bearing thereagainst thefree end portion of an elongated leai spring 3. This spring 3 has oneend portion anchored, as at 4, to a wall of the casing I with the freeend portion thereof disposed toward what may be termed the rear or outerend of the casing. This spring 3 serves to provide means whereby themember 2 is forced against a Wall of the casing I under suilicienttension to creat-e a frictional resistance to normally hold the member 2against endwisemovement through the casing I but permitting such`embodiment of the invention the member 2 is formed from an elongatedfla-t strip of material havingn one end portion returned to overlie andhave close contact with the main portion ofthe strip, as indicated at 5;whereby is provided across the memberv 2 a forwardly facing shoulder 6.

YTheforward end of the strip is also returned, as at 'I, vfora slightdistance whereby the front end of the member 2 is of increased thicknessand the inner extremity of the returned portion 'I is beveled, as at 8,to facilitate the entrancer of the thickened forward porti-on ofthememberl 2i withinfthe casing I. The rear extremity of the memberY2-is` suitably anchored, asi by solder or4 otherwise as may bepreferred, to the outer closed end 9 of an elongated sleeve I0 in whichis snugly engaged the rear portion of the casing I. The returnedportions 5 and I as comprised in the member 2 as herein embodied may besoldered or otherwise securely held to the main or body portion of thestrip.

The cutting blade B, as herein disclosed, is an elongated single edgerazor blade although I do not wish to be understood as limiting myselfto any type of blade other than such lblade be of requisite dimensionsfor effective use with the holder. The blade is inserted within theforward or front end of the casing I between the member 2 and the sidewall of the casing I. When the member 2 has its forward end portionextended as illustrated in Figure 3, as is the case when the holder isfully compacted, the blade B will extend a major distance within thecasing I withits inserted end butting the shoulder 6. By imposing pullupon either the sleeve I0 or the casing I the entire blade B may behoused within the casing I and as the thickened forward end portion 1 ofthe member 2 enters the casing I the blade vB will be eifectivelyclamped against release.

When it is desired to use the blade B the casing I and the member 2 arerelatively moved outwardly one with respect to the other until the bladeB is projected as desired beyond the forward end of the casing Iwhereupon upon inward movement of the member 2 within the casing I, thethickened end portion 'I of the member 2 will enter the casing I with aresultant tight clamping of the blade B in its desired extendedposition. It is believed to be obvious that when it is desired torelease the blade B it is only necessary to move the thickened endportion 'l of the member 2 outwardly beyond the casing whereupon theblade B may readily return within the casing l for contact with theshoulder 6.

From the foregoing description it is thought to be obvious that a bladeholder constructed in accordance with my invention is particularly Welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modi- `iication Withoutdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim: Y

1. A holder for a knife blade comprising a casing open at both ends, anelongated member snugly fitting Within the casing and having slidingmovement therethrough, said member being of a length in excess of thelength of the casing, one end portion of the member being of increasedthickness to coact with a Wall of the casing when said extremity ismoved within the casing to clamp a cutting blade between said Wall ofthe casing and the thickened extremity of the member.

2. A holder for a knife blade comprising a casing open at both ends, anelongated member snugly fitting within the casing and having slidingmovement therethrough, said member being of a length` in excess of thelength of the casing, one end portion of the member being of increasedthickness to coact with a Wall of the casing when said extremity ismoved Within the casing to clamp a cutting blade between said wall ofthe casing and the thickened extremity of the member, said member at apoint intermediate its ends being provided with a transversely disposedshoulder facing toward the thickened extremity of the member, saidshoulder providing means for engagement with the blade to move saidblade outwardly of the casing.

3. A holder for a knife blade comprising a casing open at both ends, anelongated member snugly fitting within the casing and having slidingmovement therethrough, said member being of a length in excess of thelength of the casing, one end portion of the member being of increasedthickness to coact with a Wall of the casing when said extremity ismoved within the casing to clamp a cutting blade between said Wall ofthe casing and the thickened extremity of the member, andra springwithin the casing secured to one wall thereof and contacting with theportion of the member within the casing to frictionallyengage saidportion of the member with a second wall of the casing.

4. A holder for a knife blade comprising a casing open at both ends, anelongated member snugly fitting within the casing and having slidingmovement therethrough, said member being of a length in excess of thelength of the casing, one end portion of the member being of increasedthickness to coact With a Wall of the casing when said extremity ismoved Within the casing to clamp a cutting blade between saidwall of thecasing and the thickened extremity of the member, and a sleeve carriedby the end portion of the member remote from the thickened extremitythereof, the casing being snugly and slidably received within thesleeve.
